Runway-length check by aircraft
Enter a US tail number to estimate the minimum takeoff runway that aircraft needs. Add a destination airport to check it at that field's density altitude.
N511JS — Gulfstream Aerospace Corp GVII-G500
Recommended minimum runway
9,500 ft
takeoff, sea level, with a 15% safety margin
Takeoff distance (50-ft obstacle)
8,250 ft
sea level, ISA, max weight
Ground roll
5,000 ft
before liftoff
Basis: POH-grade curated manufacturer ground-roll data for this type.
Planning estimate — takeoff only. Not a substitute for the POH.
These figures estimate the takeoff runway at maximum takeoff weight under standard conditions (ISA, 29.92 inHg, dry pavement, calm wind). They do not include landing distance, wind, weight below max, runway contamination (wet/snow/ice), slope, or obstacles — any of which can change the runway you actually need, and landing can be the limiting case for some aircraft. Always verify actual takeoff and landing performance in the aircraft's POH/AFM for the specific aircraft, weight, and conditions before every flight.
